【Abstract】 s The molecular weight and molecular weight distribution of sulfated polysaccharide 911 were determined by the GPC in this paper.The results are as follows. The weight average molecular weight ( Mw ) is 8 500±500, the percentage of Mw <10 000 is above 70% in all sulfated polysaccharide 911 moleculars; the distribution width of molecular weight Mw / Mn is 1.30±0.02.更多还原
